11. Turn the ignition switch OFF.

12. Disconnect the throttle position sensor (TPS)

connector.

13. Turn the ignition switch ON (II).

14. Measure the voltage between TPS connector

terminals No. 1 and No. 3.

Check for a short or an open in the wire

between PCM connector terminal A27 and the TPS.
If the wire is OK, replace the TPS.

Go to step 15.

15. Turn the ignition switch OFF.

16. Disconnect PCM connector C (31P).

17. Check for continuity between TPS connector

terminal No. 1 and body ground, and between
terminal No. 3 and body ground.

Check for a short to ground in the wires

between TPS connector terminals No. 1 and No. 3,
and the PCM. If the wires are OK, replace the
PCM.

Go to step 18.

18. Disconnect the shift lock solenoid connector.

19. Check for continuity between shift lock solenoid

connector terminal No. 2 and multiplex control unit
(driver’s) connector terminal B22.

Go to step 20.

Repair open in the wire between multiplex

control unit (driver’s) connector terminal B22 and
the shift lock solenoid.

20. Turn the ignition switch ON (II).

21. Measure the voltage between shift lock solenoid

connector terminal No. 1 and body ground.

Go to step 22.

Check for blown No. 9 (10A) fuse in the driver’s

under-dash fuse/relay box. If the fuse is OK, repair
open or short in the wire between the No. 1
terminal of the shift lock solenoid connector and
the driver’s under-dash fuse/relay box.

22. Connect the battery positive terminal to shift lock

solenoid connector terminal No. 1, and connect the
battery negative terminal to the terminal No. 2.

NOTE: Do not connect the terminal No. 2 to the
battery positive terminal or you will damage the
diode inside the shift lock solenoid.

23. Check that the shift lock solenoid operates.

Check for a loose multiplex control unit

(driver’s) connector. If necessary, substitute a
known-good multiplex control unit (driver’s) and
recheck.

Replace the shift lock solenoid.

1. Disconnect the key switch connector (7P) from the

steering lock assembly.

2. Connect the battery positive terminal key switch

connector terminal No. 7, and connect the battery
negative terminal to the terminal No. 5.

3. Turn the ignition switch to ACC (I), then push the

ignition key.

4. Check the key interlock solenoid operation.

A clicking sound should be heard while pushing the
ignition key, and you should not be able to turn it to
the OFF position.

Go to step 5.

Faulty key interlock solenoid/switch. Replace

the ignition key cylinder/steering lock assembly.

5. Measure the voltage between the terminal No. 7

and body ground.

Go to step 6.

Check for a blown No. 47 (20A) fuse in the

under-hood fuse/relay box. If the fuse is OK, repair
open or short in the wire between key switch
connector terminal No. 7 and under-hood fuse/
relay box.

6. Disconnect the park pin switch connector on the

shift lever.

7. With the shift lever in P and pulled back toward the

driver, check for continuity between park pin switch
connector terminals No. 1 and No. 3.

Go to step 8.

Repair open in the wires between the park pin

switch and the connector. If the wires are OK,
replace the park pin switch .

8. Check for continuity between park pin switch

connector terminal No. 3 and key switch connector
terminal No. 5.

Go to step 9.

Repair open in the wire between park pin

switch connector terminal No. 3 and the key switch
connector terminal No. 5.

9. Check for continuity between park pin switch

connector terminal No. 1 and body ground.

Check for a loose key switch connector and

park pin switch connector. If necessary, substitute a
known-good steering lock assembly.

Repair open in the wire between park pin

switch connector terminal No. 1 and ground (G401),
or repair poor ground (G401).
